How
to
Access
IP
camera
via
WAN
5.1
What’s
DDNS?
Dynamic
DNS,
also
called
as
dynamic
domain
name,
is
used
to
handle
the
problem
that
user’s
device
doesn’t
have
fixed
IP
address
while
accessing
via
Internet.
With
assist
of
DDNS,
user
can
connect
to
his/her
IP
camera
directly
via
DDNS.
If
user
wants
to
access
his/her
IP
camera
via
WAN.
The
following
two
conditions
should
be
met.
1.
User
knows
the
WAN
IP
address
or
domain
name
of
the
IP
camera.
2.
If
IP
camera
connects
to
a
router,
the
corresponding
mirror
port
of
router
must
be
set
for
IP
camera,
so
that
user
can
access
the
IP
Cam
located
in
LAN
through
WAN.
Most
users
don’t
have
fixed
IPs.
Every
time
when
the
device
connects
with
Internet,
networking
service
provider
allocates
a
dynamic
IP
to
the
device.
If
the
connection
breaks
and
rebuilds,
a
new
IP
will
be
allo
‐
cated
again.
Normally,
user
doesn’t
know
the
IP
of
device.
DDNS
feature
can
overcome
this
problem.
As
long
as
user
knows
the
dynamic
domain
name,
he/she
is
always
able
to
access
his/her
networking
device.
5.2
How
to
get
the
DDNS
account:
For
user’s
convenience,
IP
camera
binds
one
free
DDNS
account.
Each
IP
camera
has
a
unique
global
domain
name,
which
is
marked
on
device
body.
Also,
user
can
obtain
the
domain
name
via
IP
Cam
tools.
Please
re
‐
fer
the
figure
attached
below.
The
device
also
supports
third
‐
party
domain
name
resolution.
It
currently
supports
www.3322.org
and
www.dyndns.org
.
If
users
need
a
third
‐
party
domain
solution,
he
can
access
the
appropriate
site
and
apply
for
the
dynamic
domain.
Then,
fill
the
applied
domain
information
in
the
menu.
